What "affordable" means in Honolulu: area median income, income limits and rent caps

Housing & policy · Published 2026-10-21

"Affordable housing" sounds like housing that ordinary people can afford. In practice it is a technical label attached to homes whose rents or prices are capped relative to a local income figure. In Honolulu, where incomes and costs are both high, the result can surprise people: a two-bedroom unit labelled affordable at 80% of area median income can rent for $2,772 a month.

Area median income, in plain terms

Almost every housing program in the United States is pegged to area median income, or AMI. Each year the U.S. Department of Housing and Urban Development (HUD) estimates a median family income for each metropolitan area and county, then publishes income limits for household sizes from one to eight people. For the City and County of Honolulu, the City's income guidelines page cites a 2025 median family income of $129,300.

HUD itself publishes three main limits for the Honolulu area:

• Low income, often called 80% AMI;
• Very low income, often called 50% AMI;
• Extremely low income, often called 30% AMI.

The labels are approximations. HUD's methodology adjusts the limits for high-cost areas and caps, so the "80%" figure is not always exactly 80% of the median. The City's Department of Planning and Permitting (DPP) then uses HUD's limits to calculate higher bands at 100%, 120% and 140% of AMI for its own programs.

The City's 2026 income limits

The figures below come from DPP's 2026 income limits and maximum rents, effective May 15, 2026, based on HUD limits effective May 1, 2026.

For context, the City's Section 8 voucher program lists a 2026 income limit of $77,000 for a four-person household and $53,900 for one person, on its program page. Those figures correspond to HUD's very-low-income band.

How maximum rents are set

For units restricted at 80% AMI, DPP publishes two sets of maximum rents. One is calculated as 30% of the income limit, adjusted for family size and unit type. The other uses HUD's Fair Market Rents for Honolulu. Both include utilities: if the tenant pays electricity or water separately, the maximum rent must be lowered accordingly.

At 100% AMI, the 30% method gives maximum rents of $2,887 for a one-bedroom and $3,465 for a two-bedroom. These ceilings are what make "workforce housing" financially workable for developers; they are also why such units rarely help people leaving homelessness.

A worked example: a family of four

Take a household of four. At the 80% limit of $123,200 a year, 30% of gross monthly income is about $3,080, comfortably above the $2,772 maximum rent for a two-bedroom unit restricted at 80% AMI. Now take the same family at the City's Section 8 limit of $77,000 a year. Thirty percent of its monthly income is about $1,925, well below both the 80% AMI rent cap and the HUD Fair Market Rent of $2,642 for a two-bedroom. On paper, both families qualify for "affordable" housing; in practice, only the first can rent an 80% AMI unit without exceeding the 30% benchmark.

Who "affordable" leaves out

An affordable unit at 80% AMI is designed for a household earning close to the 80% limit. A household earning much less can still be rent-burdened in it. Consider a one-person household working full time at $20 an hour, which is about $41,600 a year before tax. Thirty percent of that income is about $1,040 a month, roughly half the maximum rent for an 80% AMI studio. For that worker, only units restricted at deeper levels (30% or 50% AMI) or a rental subsidy would bring rent within the 30% benchmark that HUD uses to define cost burden.

That gap is why housing advocates distinguish between:

• Workforce or moderate-income housing (roughly 80% to 140% AMI), which can be built with limited subsidy in a high-cost market;
• Low-income housing (50% to 80% AMI), usually financed with federal tax credits or state loans;
• Deeply affordable housing (30% AMI and below), which almost always needs ongoing rental subsidy or public ownership, and which is what most people exiting homelessness need.

The state's kauhale program is an example of policy aimed at the bottom band: Act 309 of 2025 defines kauhale to include communal affordable housing projects charging rents of no more than 30% of the area median income level (see our kauhale explainer).

Questions to ask about any "affordable" project

1. Affordable to whom? Check the AMI level of the restricted units. "Up to 140% AMI" and "30% AMI" describe very different tenants.
2. How many units, and for how long? Affordability restrictions often expire after a set period.
3. Are utilities included? Maximum rents include utilities; if tenants pay them separately, the rent cap should be lower.
4. Is there rental assistance? Projects that accept Housing Choice Vouchers or have project-based subsidies can serve much lower incomes.

Where to check current figures

Income limits and Fair Market Rents change every year, usually in the spring and autumn respectively. The City's DPP publishes its limits on honolulu.gov; the State's Hawaiʻi Housing Finance and Development Corporation publishes its own income, rent and sales price guidelines for each county; and HUD's data portal publishes the underlying federal limits. Always check the year printed on the table you are reading.
